TUCKER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 695,735, dated March 18, 1902.

Application filed June 10, 1901.

T ctZZ whom it may concern:

Be it known that I, RICHARD J. KELLEY, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Tuckers for Sewing-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to a novel device designed to be applied to the bed-plate of a sewing-machine adjacent to the feed mechanism and needle for the purpose of accurately guiding the fabric fed to the needle in folded I 5 condition to produce tucks or plaits.

The main object of the present invention is to provide a device which can be readily attached to sewing-machines of any wellknown construction and which can be quickly and conveniently adjusted to form tucks of different widths and also to form the same various distances apart, as may be desired.

Furthermore, the object is to produce a device which shall be simple in construction,

efficient and reliable in its operation, and alsoinexpensive in its manufacture; and to that end the invention consists in the improved construction and arrangement of the component parts, as hereinafter fully described, and set forth in the claims.

In the accompanying drawings, Figure 1 is a plan view of my improved tucking device. Fig. 2 is an inverted plan View. Fig.3 is a side view of the same. Figs. 4 and 5 are detached plan views of the respective attaching arms, and Fig. 6 is a detail perspective view of the main plate.

Inasmuch as the construction of sewingmachines is well known and my improved o tucking device is applicable to any sewingmachine, it is unnecessary to show or describe said machine. Therefore I will refer only to such parts as are required to make the invention clearly understood.

Referring to the drawings, A denotes the main plate of the tucking device, which is preferably formed from a sheet-metal blank. Said plate is bent transversely at its intermediate portion, so as to dispose the front portion thereof into a higher plane than the rear portion and parallel therewith. The in- Serial No- 63,848.

termediate offset (1 serves to guide the fold of the fabric during the process of stitching it, and I therefore term it the folding-guide. The rear portion of said main plate is folded down and forward onto its under side and terminates beyond the offset a, as indicated at b, which projecting portion I term a guidelip. Said lip aids in guiding the fold of the fabric to the needle, (indicated at c.)

The raised or front portion of the plate A is formed with two oppositely-disposed flanges d, projecting upwardly and inwardly from its side edges. The rear portion of said plate A is provided with a pair of rigid upwardlyprojecting pivots e e and with a hub f between said pivots, which hub is of a height to bring its top on a level with the front portion of the main plate A and is provided with a screw-threaded socket g.

g g denote the two arms by which the device is attached to the table or bed-plate of the sewing-machine. Said arms are slotted longitudinally, as shown at h h, and are provided at one end with perforations'i 2', whereby they are connected to the aforesaid pivots e e. j is a set-screw which passes through the slots of said attaching-arms at their point of crossing and is adapted to engage a screwthreaded socket in the top or bed-plate of the machine, said socket being provided on all machines. As is well known, the position of the latter socket is different in the various makes of machines. Therefore it will be seen that by reason of the attaching-arms being slotted longitudinally and crossing and provided with the set-screw they can be readily placed at different angles to each other, and thus accommodate themselves to any machine. Said slotted arms also serve to permit 0 the main plate A to be shifted both longitudinally and laterally to adjust the foldingguide toward and from the needle and also in proper alinement with the feed of the sewingmachine. On the front portion of said main plate is supported the supplemental plate B, which engages the aforesaid flanges d d and is formed with a longitudinal slot a. Said supplemental plate is bent transversely at its free end portion to form the tuck-gage 10: with its rearwardly-extending tongue I). Said tuck-gage is adapted to receive the pre viously-formed tuck during the stitching of each succeeding fold and serves to regulate the distance between the tucks and also to maintain the rows of stitches in proper alinement.

Through the slot a of the supplemental plate passes a set-screw c, which engages the socket g and terminates therein to prevent its interfering with the shifting of the main plate on the table. The head of said screw bears on top of thesuppleinental plate and clamps the same on the main plate.

Upon the upper face of the supplemental plate is provided a scale which serves to indicate the distance between the tuck-gage and folding-guide, thus facilitating the setting of said tuck-gage.

It will be understood that the supplemental plate may be of various lengths, according to the nature of the work. Said supplemental plate bears on the ends of the aforesaid pivots e e, and thus retains the attaching-arms g g in their connection therewith. The arms can be easily disconnected from said pins, if required, by loosening the set-screw c and shifting the supplemental plate forward sufficiently to carry its rear end off from the pivoted ends of the arms g.

What I claim is 1. In a tucker for sewingmachineathe combination of a laterally and longitudinally adjustable main plate bent transversely so as to dispose oneportion thereof in a higher plane than the remaining portion and parallel therewith, and provided on its lower portion with two pivots,said bend forming a folding-guide, longitudinally-slotted attaching-arms connected to said pivots and crossing each other and clamped jointly and adjustably on the table, and a supplemental plate mounted longitudinally adjustable on the higher portion of said main plate and provided with a tuck-gage at its free end as set forth.

2. In a tucker for sewing-machines,the combination of a laterally and longitudinally adjustable main plate provided with two pivots, attaching-arms connected to said pivots and provided with means for clamping them jointly on the table, a folding-guide on said main plate, a supplemental plate mounted longitudinally adjustable on the main plate and bearing on the ends of said pivots to retain the attaching-arms in their connection therewith and provided with a tuck-gage on its free end as set forth.

3. 'The combination of the main plate formed with a raised front portion and provided on its rear portion with two pivots and with a screw-threaded socket between said pivots, longitudinally-slotted attaching-arms connected to said pivots and crossing each other, the attaching-screw passing through the slots of the arms, a folding-guide formed integral with the rear portion of the main plate, a supplemental plate mounted on the front portion of the main plate and provided with a longitudinal slot and having its free end formed with the tuck-gage, a set-screw passing through the said slot and into the socket of the main plate and terminated therein as set forth.

4. The combination of the main plate formed with its front portion in a higher plane than its rear portion and parallel therewith and provided at the intermediate olfset with a guide-lip projecting from the rear portion of the plate, a hub projecting from the top of the rear portion of the plate and formed with a screw-threaded socket, a supplemental plate mounted on the front portion of the main plate and formed at one end with a tuck-gage and provided in the opposite end portion with alongitudinal slot,asetscrew passingthrough the slot and into the aforesaid socket and terminated therein, and attaching-arms pivoted to the rear portion of the main plate at opposite sides of the tubular hub and clamped jointly and adjustably on the table as set forth.

5. The combination of the main plate formed with its front portion in a higher plane than its rear portion and with the intermediate offset to constitute the folding-guide, said front portion having its opposite edges formed with parallel guides, the rear portion folded under onto itself and projecting beyond the aforesaid offset,a screw-threaded tubular hub projecting from the top of the rear portion of the plate to a height even with the plane of the front portion of the plate, and pivots projecting from the top of the plate at opposite sides of the said hub in combination with attaching-arms connected to said pivots and provided with longitudinal slots, a set-screw passing through said slots and fastening the arms jointly to the table, the supplemental plate mounted on the front portion of the main plate between the guides thereof and provided with a longitudinal slot and formed with a tuck-gage on its free end, and a clamping-screw passing through said slot and into the aforesaid hub of the main plate, all construcled and combined in the manner set forth and shown.
